Flume 2 Smart Water Monitor vs Heiman Smart Water Leakage Sensor

They answer different questions. The Heiman Smart Water Leakage Sensor is the easier recommendation for a single fixture, with a loud local alarm and a five-year cell. The Flume 2 Smart Water Monitor wins when the leak could be anywhere in the property and you also want usage data.

What each one watches. The Heiman Smart Water Leakage Sensor only knows about water that touches its own contacts. The Flume 2 Smart Water Monitor reads the water meter, so it can flag a leak anywhere on the property, including ones that never reach a floor.

Yes, the sensor itself still sounds its 75 dB alarm out of the box, but app alerts, remote notifications and automations need Heiman's gateway, which many single-unit listings do not include. The Flume 2 Smart Water Monitor reaches its app through the bridge in the box.

No. It has no on-device sound or light, so alerts arrive through the app, while the Heiman Smart Water Leakage Sensor sounds a 75 dB alarm in the room.

Anyone who wants an affordable, waterproof puck with a loud local alarm under a sink, water heater or washing machine, and who is fine adding Heiman's gateway later for remote alerts.

Homeowners who want whole-property leak detection without plumbing work, especially with irrigation or surprise water bills, and who prefer Google Home or app alerts over a physical siren.
